主　　题：surfactant release stabilized 

摘      要：Water-in-oil droplets have emerged as promising microreactors for high-throughput biochemical analysis due to their features of reduced sample consumption and automated *** a typical screening application,droplets are often trapped for continuous monitoring of the reaction over an extended period,followed by the selective retrieval of targeted droplets based on the after-effect of biochemical *** techniques for droplet trapping are well developed,retrieval of targeted droplets mainly demands complicated device fabrication or sophisticated ***,facile and rapid selective droplet release is achieved by utilizing a new class of photoresponsive fluorosurfactant based on plasmonic *** intense photothermal response provided by this novel photoresponsive fluorosurfactant is capable of vaporizing the fluorocarbon oil at the droplet interface under laser illumination,resulting in a bubble releasing a trapped droplet on demand.A fully automated fluorescence-activated droplet release platform has also been developed to demonstrate its potential for droplet-based large-scale screening applications.
